Title: Method for manufacturing semiconductor element
Inventor: LEE SEONG GWON
IPC: H01L21/324
Filed: 1998-12-30
Abstract: PURPOSE: A semiconductor element fabricating method is provided to prevent an oxidization of a copper thin film and to constantly maintain a threshold voltage of MOSFET by changing a layout of a metal wiring and injecting hydrogen atoms before a heat treatment process is performed thereby performing an annealing process in a nitrogen atmosphere. CONSTITUTION: When a heat treatment process for a semiconductor element having copper wires(1,13,15,17) therein initiates, hydrogen atoms(10) are injected into a front surface of a substrate(100) by an ion implantation process before a heat treatment process is performed. The hydrogen atoms are distributed on surface layers of insulation films(2,3,4,12,14,16) which are formed between the copper wires(1,13,15,17) and the copper wiring layers(20), so the heat treatment process is performed in the nitrogen atmosphere.

Abstract: PURPOSE: A DLL(delay locked loop) circuit is provided to reduce time elapse until a lock-on state when the DLL circuit starts in a normal mode or resumes a normal mode from a standby mode. CONSTITUTION: The DLL circuit comprises: a variable delay circuit for variably delaying a first clock; a second clock created by delaying an output of the variable delay circuit for a predetermined amount of time; a phase comparator creating resultant signal of the phase comparison between the first clock and the second clock; a delay control circuit supplying a delay control signal for controlling delay time to the variable delay circuit in response to the resultant signal of the phase comparison. The delay control circuit creates a single delay control signal reducing the delay time of the variable delay circuit to a minimum for the normal mode of the DLL circuit and creates binary delay control signal modifying the delay time of the variable delay circuit to binary digit when the DLL circuit starts a normal mode. Therefore DLL circuit can go to a lock-on state in a short time because a phase control is carried out by a binary shift method during a start mode and stabilize because the phase control is performed by a single shift method during a normal mode.

Abstract: PURPOSE: A method for preventing AV mode 16:9 zoom cancellation for a VTR is provided so that 16:9 zoom cannot be converted to 4:3 mode when a user operates a channel up/down key by mistake. CONSTITUTION: When a television is turned on(S10), a microcomputer judges whether a user converts a mode to a VTR reproduction mode by using a remote controller or key input unit(S20). In the VTR reproduction mode, the microcomputer confirms whether the user reproduces 16:9 mode(S30). When a video tape is reproduced in the 16:9 mode, the microcomputer judges whether a channel up/down key is inputted from the remote controller or channel input unit(S40). At this time, when the user mistakenly presses the channel up/down key, the microcomputer confirms whether a level of an eighth pin of 21PIN EURO SCART is high(3 to 5V)(S50). If so, the microcomputer maintains the 16:9 mode, namely prevents the 16:9 mode from being converted into 4:3 mode(S60). On the other hand, when the level of the eighth pin is low, the microcomputer recognizes a current broadcasting as a CANAL broadcasting, cancels the 16:9 mode, and starts the 4:3 mode(S70).
